The Electrochemical Synthesis of Transition-Metal AcetylacetonatesS. R. Long, S. R. Browning, and J. J. LagowskiThe electrochemical synthesis of transition-metal acetylacetonates can assist in the transformation of an entry-level laboratory course into a research-like environment where all members of a class are working on the same problem, but each student has a personal responsibility for the synthesis and characterization of a specific compound.Long, S. R.; Browning, S. R.; Lagowski, J. J. J. Chem. Educ.2008, 85, 1429.

Fog Machines, Vapors, and Phase DiagramsEd VitzThis series of demonstrations elucidate the operation of commercial fog machines using common laboratory materials and can be adapted for elementary through tertiary levels. The formation of fogs is discussed in terms of the phase diagram for water and other chemical principles.Vitz, Ed. J. Chem. Educ.2008, 85, 1385.

Floating Squares (GCMP)David M. WhisnantFloating Squares: this is a resource in the collection "General Chemistry Multimedia Problems". In this problem we will coat a piece of notecard with graphite (from pencil lead). We then will float the piece in two beakers containing water and a second solvent. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
